A mild steel sleeve 14 cm inside diameter and 20 cm outside diameter is subjected internal pressure of 45 N/mm. The sleeve is rigidly hooped so that the ero. Determine the values of the radial and circumferential stresses outer surfaces. Proceed from Lame's equations and neglect axial stresses. v = 0.3 (Ans: inner: -45 N/mm, +2.2 N/mm², outer: -32.8 N/mm, -9.9 N/mm)
P.1.9. A bar of mild steel has a diameter of 75 mm and is placed inside a hollow aluminum cylinder of internal diameter 75 mm and external diameter 100 mm; both bar and cylinder are the same length. The resulting composite bar is subjected to an axial compressive load of 1000 KN. If the bar and cylinder contract by the same amount, calculate the stress in each. The temperature of the compressed composite bar is then reduced by 150°C but...
The assembly consists of two red brass C83400 copper rods ABAB and CDCD of diameter 30 mmmm, a stainless 304 steel alloy rod EFEF of diameter 40 mmmm, and a rigid cap GG. The supports at AA, CC and FF are rigid.Modul of elasticy for the copper is EcopperEcopper = 101 GPaGPa. Modul of elasticity for the steel is EsteelEsteel = 193 GPaGPa.(a) Determine the average normal stress developed in the rod ABAB.(b) Determine the average normal stress developed in the rod CDCD.
